Real Method for solving this Question:

For Shortcut, use this method:-
Number of Planks required to stop the bullet = n/2 + 1 (if n is even) and = n/2 + 0.5 (if n is odd).


8. C
ΔT = 0.5 T α Δθ
Δt = ΔT​ / T ′
But T ′=T
∴ Δt = 0.5 * ​αΔ * θ * (t) (Use this formula for shortcut in Entrance exams)
      = 0.5 ​× 0.000012 × 20 × 24 × 3600
      = 10.37 seconds
At higher temperature length of pendulum clock will be more. So time period will be more and it will lose the time.


9. B

10. D
The rainbow is caused by light from the sun (or moon) interacting with raindrops falling from the air. These raindrops are mostly round. A ray of light entering such a droplet is bent (refracted) and decomposed into all possible colors (wavelengths) which the white light consists of. The ray then reflects internally in the droplet, and emerges roughly into the direction it came from when it entered the drop. Since the rays of the different colors all exit at slightly different directions, we see a color band in the sky.
The colors are produced by a phenomenon called dispersion. Dispersion causes white light, which consists of all possible colors to break up into all components, when the light travels from one medium (e.g. air) to another (e.g. water). The different colors of light have all slightly different directions, so if we look in a certain direction in the sky we can see the spectrum.
VVI Line : Violet light scatters the most while red light scatters the least because violet has shorter wavelength and red light has larger.


11. D
A refrigerant is a substance or mixture, usually a fluid, used in a heat pump and refrigeration cycle.
In most cycles, it undergoes phase transitions from a liquid to a gas and back again.
Many working fluids have been used for such purposes. Fluorocarbons, especially chlorofluorocarbons, became common place in the 20th century, but they are being phased out because of their ozone depletion effects.
Other common refrigerants used in various applications are ammonia, sulfur dioxide, and non-halogenated hydrocarbons such as propane.
Freon is a registered trade name of DuPont, which it uses for a number of halocarbon products.
They are stable, nonflammable, moderately toxic gases or liquids which have typically been used as refrigerants and as aerosol propellants.


12. C
Law of multiple proportions states that if 2 elements form more than one compounds between them, then the ratios of the masses of the second element which combine with a fixed mass of the first element will be ratios of small whole numbers.

In N2​O and NO, the ratio of weight of N reacting with a constant weight of O is 2:1.


13. A
2−chloropentane is branched. So, its surface area is lower than that of 1−chloropentane. If surface area decreases the ability of molecules to interact through vander-waal forces decrease, so the boiling point decreases. So, 1−chloro−pentane has highest boiling point.
Remember: Boiling point is directly proportional to molecular weight and inversely proportional to branching.


14. C
PH3​ is a Lewis base as this has lone pair on P which can donate its electrons pair to electron deficient species.


15. A
Oxygen molecule contains 2 unpaired electrons and is paramagnetic in nature.


16. D
Cell biology is the study of all aspects of cells and their components including their structure, biochemistry, development and physiology. It treats the cell as fundamental unit of life. So, the correct answer is 'Cell biology'.

17. A
The sun is called the ultimate source of energy because it is the source of almost all energies of the earth. Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Animals eat plants and use that same chemical energy for all their activities.


18. C
In case of true coelomic cavity of vertebrates, the cavity is lined by mesodermal cells. The pseudocoelom is a body cavity lying inside the body wall of certain organisms like the nematodes. This cavity bathes the internal organs. The organs like the alimentary system and the reproductive system are surrounded by this cavity. This body cavity is called as a pseudocoelom. It is called as pseudocoelom because it is not fully lined by mesodermal cells. The cavity is derived from blastocoel.


19. C
The infective stage of Plasmodium is a minute organism called sporozoite. When the mosquito bites man, sporozoites present in the salivary gland of female Anopheles mosquito are injected into the blood of the man. These sporozoites are spindle-shaped or sickle- shaped uninucleate organisms capable of wrigging (worm-like) movements. Each sporozoite consists of elastic pellicle, cytoplasm and nucleus.

The life cycle of Plasmodium that infect humans follows three stages: 
(I) infection of a human with sporozoites; 
(II) asexual reproduction and 
(III) sexual reproduction. 
The two first stages take place exclusively into the human body, while the third one starts in the human body and is completed into the mosquito organism. The human infection begins when an infected female anopheles mosquito bites a person and injects infected with sporozoites saliva into the blood circulation. That is, the first life stage of plasmodium (stage of infection). The next stage in malaria life cycle is the one of asexual reproduction that is divided into different phases: the pre- erythrocytic and the erythrocytic phase. Within only 30- 60 minutes after the parasites inoculation, sporozoites enter through blood circulation to their first target, the liver. The sporozoites enter the liver cells and start dividing leading to schizonts creation in 6-7 days. Each schizont gives birth to thousands of merozoites (exoerythrocytic schizogony) that are then released into the blood stream marking the end of the exoerythrocytic phase of the asexual reproductive stage.


20. D
The honey bees exhibit 2 types of dance, the round dance and the tail-wagging or waggle dance. It is meant for communication the location for the sources of food.
The honey bee dance is a method by which:
- a honey bee scout tells a swarming colony about the location of a potential new home. In doing so, they engage in tail waggling.
- a honey bee communicates to its sisters the distance and location of food and also water.


21. A
Sexual reproduction of Spirogyra involves conjugation, which may be defined as a primitive type of isogamy called aplanogametic isogamy. In this type of isogamy, the entire protoplasmic contents of vegetative cells (i.e., Gametangia) function as gametes.


22. D
In DNA nitrogenous base pairs shows complementary base pairing. The complementary base of Guanine is the cytosine, while adenine pairs with thymine.


23. D
If a cell is kept in hypertonic solution exosmosis occurs and water moves out from the cell into the solution. This process is called as exosmosis and leads to plasmolysis. 
In a plasmolyzed cell the cell contents or protoplasm leaves cell wall and gets shrunk. If the same cell is now placed in a hypotonic medium or distilled water, it will gain water due to endosmosis and again become turgid. This cell is now called as deplasmolysed cell.


24. A
Phyllode is a modification of leaf or petiole. It is green in colour and is able to carry out photosynthesis. It is a xerophytic adaptation. It reduces the rate of transpiration in xerophytic plants like Opuntia.


25. B
The Krebs cycle which takes place in the mitochondria of the cell helps in generating energy and occurs immediately after glycolysis. The cycle which starts with the 3- carbon molecule called pyruvic acid, breaks it down into acetyl coenzyme A which then further combines with oxalo-acetic acid to form citric acid. Krebs cycle is also referred to as citric acid cycle.


26. B
Hint: Number of non empty proper subset = 2^n – 2 
= 2^4 — 2 
= 16 - 2 
= 14.


27. A



28. B
Let, B = A + A^T
⇒B^T = (A + A^T)^T
=A^T + (A^T)^T
=A^T + A = B
Hence B=A + A^T is a symmetric matrix.


29. B


30. C
Camel lacks omasum hence, is called pseudo-ruminant.


31. B
